the meshes the disk 5 may be adjusted by means of a clamp 45, which. may be screwed up and down by means of a thread on the machine har, the length of the meshes being determined by means of a lscale which is clamp i y Now i accordance with this invent-ion the loopers 6 are suspended at their upper 'ends 9 and within the tubular fabric over the needles 7, so that they are easily accessible with the needles, may be watched when in operation. For this object a ring 10 carrying the-loopers is lirmly connected with the body 3 of the machine, which ring isproln thev upper guide 11a circular ring 13 is mounted, to which the loopers G are suspend jfoi" which object they have a slot 14, so tha -v`they can swing freely.

The needles 7 lie in the ordinary needle dial 15 and are retained by segmental upper fastening plates 1G. Now in order to be able to release these in orderv to change the needles 7, they are arranged so as to be lifted. For this purpose the plates 16 are con nected with screws 17, which pass through the ring 10 carrying the loopers, and their -heads are provided with a rectangle 18, in lorder td'a'llow of their being easily turned.

For raising the plates 16 a separate lifting device is also arranged on the disl{ shaped part of the machine frame This consists of a bearing frame or bntket 19 in the head 20 of which a spindlefxniay be screwed, which for this objeolao-provded .with a hand 'crank 22.

has for this object a pin 2e which engages in an angular slot 25 of the sleeve and Works after the manner of a bayonet Joint. Now if one of they plates 16 is to be ll'l'ted,

the machine is turned until the sleeve 23 comes over the screw 17 of the plate 1G in question. The sleeve 2S is then rotated until the pin 2e passes out of the horizontal arm of the slot 25 into the vertical one, whereupon the sleeve 23 is lowered, that is to say the coupling with the spindle 21 may be completed. Simultaneously with the lifting of the plates 1G, the loopers G must. also be lifted, as they would otherwise be in the way. For this object they are provided with a shoulder 28 beneath which a segment piece 27 engages, which is connected with the spindle 2l by a bar 2G. Now if the spindle 2l be rotated, in addition to the plate 16 in questiomthe looper 6 belonging to it is also lifted, and thus rests against an elbow piece 29. The loopers 6 are provided at their lower end with a beak 30hy means of which they form the loops in the ordinary way, and also with a projection 31 for pushing forward the loops of the old meshes onto the beard of the needles 7. Newby this invention the loopers (i are also provided with a notch 32, which equalizes the meshes in respect of exactness and brings them into the correct position, and Atinally with a iiattened part 33, which allows of the pressing wheel S being arranged almost vertically and also allows of the loopers passing unimpededly:

New the operation of the machine in accordance with this invention is as follows 2 The loopers 6 located in the guide slots .of the parts l1 and l2 of the ring l0 are conveyed to the fixed cams 36 and 38 by the rotation of the frame 3' and thereby the loopers G receivetheir up and down and lateral swinging movements by means of the inclines 4l, 42, and also vby means of the' internal formation of the cam 3G, where upon the operation of forming the meshes takes place as followsz-At the commencement of the operation the loopers 6 drop;

into the needles 7 and form the loops (Fig. 2) in the ordinary `way. The loopers 6 traveling on the cams now run up on the inner side of the latter, so that they are rocked forward (Fig. 3).. The loops are thereby pushed forward by the beals 30 of the loopers and pass under the beards of the needles 7 which are not yet closed. I1n-. mediately behind the loops the old meshes are brought by the projection 3l over the beards which are closed inl the meantime now lifted by their cams (Fig. 4) whereupon the projection 31' ta 'es off the old meshes on the looper 6 roclging farther forward, that is to say, throws them ed over The loopers are.A

sink into their previous position andthe' notch 32 is pressed between the now finished meshes, thus preventing the meshes a ain passing back onto the needle beard, Aan simultaneously the meshes are thereby exactly equalized in length (Fig. 6). The old meshes being spread, and the new meshes formed, the loopers 6 are lowered once more, so that the beak 30, or its notch 32 enters between the meshes, thus effecting their equalization. The looper is lowered by means ofthe cam 38. In the lmeantime the pressing wheel'has again released the latches, so that themeshes and the fabric, kon the return of the. loopers 6, are again carried back behind the needle' latches. The loopers 6 are then lifted, so that they come into the previous initial' position, whereupon the operation is repeated. The meshes are thus .constantly under the action of the loopers during the entire formation of the meshesso that'an incorrect formation ofthe meshes is avoided.

I declare that what I claim is l. In a circular knitting machine, the
